On Day #9 of his month-long series on the streets of New York City, graffiti artist Banksy has gone dark with a depiction of a shootout between armed men and hi-tech horses wearing night-vision goggles.

The mural, located on the Lower East Side, appears to be painted on a car and the side of a truck.

UPDATE: A tipster tells us this piece is on Ludlow between Rivington and Stanton Streets. He also said that some people attempted to hop the locked chain-link fence to get a closer look. One guy tried to take the orange cone that's part of the work, but he left it after he was booed by the crowd, our tipster said.
